Abstract
This is a project of mechanical machine, which allowed smoothly change rpm ratio between input and output with principle of conservation of energy (no loss of power) while changing the ratio.
Description
This invention relates to the new and improved automatic transmission. The constant problem to create better transmission which allows for better matching between input rpm and output rpm and smoothly changing ratio between rpm's was addressed by many inventors with better or worse results. Most of these designs allow smoothly rpm change with significant power loss. In this design, I am trying to show the other solution with virtually no power loss. The only power loss will come out of imperfections of building moving parts and it could be in range of 1%.
Many mechanical machines are powered by, motors or engines and it was always problem of matching rpm's. In motor vehicles for example to do that task, transmission are used. These transmissions can not match perfectly engine to wheels due to the limited amount of gears they contain. There was always need to create an automatic transmission which allows smoothly change ratio between rpm's with no power loss.
This design try to solve this problem and allows smoothly change rpm's between input and output with no power loss.
Accordingly, two advantages of my invention are:
(a) To provide almost perfect match between engine and wheels.
(b) To provide cost saving production due to simplicity of design.
In accordance with the present invention described here, torque converter comprise of housing divided into two chambers by divider 4, two independent rotors (2 and 5) and two seals (3 and 6) preventing liquid getting out of housing.
- 1 Body of the converter.
- 2 Rotor of the first pump.
- 3 Left wall, sealing body of the converter on the left side.
- 4 Divider divides body of converter to two chambers.
- 5 Rotor of the second pump.
- 6 Right wall, sealing body of the converter on the right side.
From description above a great advantage—the simplicity of my converter become evident.
In FIG. 5 body was shifted to the left, so chamber A increased volume and chamber B decreased volume. In this case pump A is pumping much more liquid, so rotor 5 of pump B must increase speed compare to rotor 2. The increased speed of rotor 5 will force shaft S of rotor 5 to run around axle C over dotted line as FIG. 5A shows.
In FIG. 6 , the body was shifted to the right, so rotor 5 will decrease speed compare to rotor 2, because much less liquid is pumped. In this case FIG. 6A shows the exactly opposite direction of movement of S around C.
Thus the reader will see that my method of torque converter provides much better matching engine—wheels connection.
While my above description contains many specificities, these should not be construed as limitation on the scope of the invention, but rather as an exemplification of one preferred embodiment thereof. Many other variations are possible. For example, instead two pumps with common body, two pumps with common shaft and separate bodies could be used and output speed could be collected as differential speed between bodies of pumps.
Accordingly, the scope of the invention should be determinated not by embodiments illustrated, but by the appended claims and they legal equivalents.
Claims (1)
1. A method of torque conversion comprising the steps of:
providing two variable displacement pumps connected hydraulically such that all liquid pumped by the first pump is sent to the second pump and back creating a closed loop;
driving an output by rotation of the first pump;
driving the output by rotation of the second pump;
rotating the output at a speed equal to the differential speed of rotation between the first and second pumps; and
controlling the speed and direction of rotation of the output by varying the displacements of the first and second pumps.
